Multiple independent sources confirm that U.S. federal safety regulators have recently expanded their investigation into Tesla's Full Self-Driving (Supervised) software. The primary focus of this probe is the system's performance in poor or low-visibility weather conditions, such as heavy rain, fog, or snow. Regulators are concerned that the software may not adequately detect obstacles or respond appropriately in these challenging environments, potentially increasing the risk of accidents. This escalation in scrutiny signals heightened regulatory attention on Tesla's autonomous driving claims and could have significant implications for the company's ability to deploy or update its software in the U.S. market.

The investigation's expansion raises the possibility of a recall campaign or other enforcement actions against Tesla, depending on the findings. If regulators determine that the Full Self-Driving (Supervised) software poses a safety risk under certain weather conditions, Tesla may be required to issue software updates, limit the use of the feature, or even recall affected vehicles. This development adds further uncertainty for investors and customers, as the outcome could impact Tesla's reputation and its timeline for achieving fully autonomous driving capabilities. The company has not yet issued a formal response to the latest regulatory actions.

In a separate development, Tesla has reportedly continued to adjust its pricing strategy in key global markets, including recent price reductions for several models in China and Europe. These moves are seen as efforts to maintain market share amid intensifying competition from both established automakers and new entrants in the electric vehicle sector. While price cuts may help boost short-term sales volumes, they also raise questions about Tesla's profit margins and the sustainability of its aggressive growth targets in an increasingly crowded marketplace.
